My GE PSS26MSTE has been turning into a block of ice lately. My 4 year has learned how to open the door but isn't to keen on making sure the door is completely closed.

How can I initiate a defrost cycle test? Are there jumpers on the board or is it done with the temperature controls. I used the hair dryer tonight to get it back up and running but am hoping there isn't a bigger issue.

Also is there a way to put my ice block maker into a diagnostic mode to test the various compenents?

Great Samuri Repair Man, I have reviewed the most sacred scroll and still cannot snatch the pebble from your hand. My model has 2 digit temperature numbers so I can't set both to 5. How do I enter diagnostic mode?

i dont put much stock in the built in diagnostics on these fridges. i prefer to jumper the heater at the board and see if it heats. if it does heat i check the evaperator thermistor. if it doesnt heat you have either a bad heater or limiter.

unplug the ref. go to the mainboard right rear on the back of the ref. locate a 3 prong connector..usually blue. on the board it should be marked defrost,compressor and main (?). run a jumperwire across defrost and main leaving the blue connector on the board. plug the unit in. turn it off on the controls. you then can either check for amp draw of the box or open up the freezer door and watch and listen for the defrost heater. if heater comes on it will tell you that the heater and "defrost terminator" are good. it really isn't a defrost terminator just a safety device. defrost is terminated by the board which gets its info from the evaporator thermistor.
